Title: Magnetic recording system
IPC: H04N5/782
Filed: 1969-12-11
Abstract: 1285745 Television INTERNATIONAL BUSINESS MACHINES CORP 11 Dec 1969 [14 Jan 1969] 60453/69 Heading H4F In a video signal recording system a magnetic tape is moved past a multi-gap recording head and each gap is sequentially energized with a signal proportioned to the intensity of an elemental area of a line scan of the image to be recorded. In Fig. 1 a pattern of magnetization representing image 11 is recorded on tape 10 by scanning the image from bottom to top successively along paths A, B and C, the resulting signals being recorded in rows of bit cells along tape 10, one cell from each row being associated with each scan A, B, C &c. The mode of recording is such that when a black area is scanned an area 19 of the cell 16 is magnetized in one direction whilst the remainder 20 of the cell is magnetized in the opposite direction, area 19 being large compared with area 20. The opposite is so when a white area is scanned e.g. area 21 is small compared with area 22. Although only three tracks on the tape are shown for each of the areas 12, 13 and 14 of the image, a total of about 500 tracks is usually employed. In Fig. 2 the windings 41 of the recording head are sequentially energized by the output from an image electronic scanner e.g. an orthicon, vidicon or image disector, each line scan of which is initiated by a pulse from timing control 32. A train of pulses is simultaneously fed from control 32 to counter 35, the outputs of which sequentially gate sample and hold (SH) circuits 37, 42 &c. The output of each SH circuit, which represents the amplitude of the signal on line 31 is applied to the junction of a resistor and capacitor and to the input of a flip-flop circuit which energizes the associated recording winding 41 for a period proportional to the amplitude of the signal from the SH circuit. The finaltwo stages 46 of counter 35 are not utilized since they accommodate the fly-back time for each scan of scanner 30. In a second embodiment (Fig. 4, not shown) the tape may be held stationary while each transverse scan is recorded, and the SH and flip-flop circuits may be replaced by an amplifier which develops a current analogue representing the scanner output, and a switching circuit. The tape prior to recording is preferably magnetized in the opposite direction from the recorded areas. Playback may be effected using a magnetooptic readout the tape being moved intermittently (Fig. 6, not shown) the resulting optical image being directly viewed or televised. For colour recording, the three colour pictures may be recorded as separate images, their magneto-optic images being optically superimposed using either colour sources or filters.

Title: Communication system
IPC: H04L5/06
Filed: 1969-12-11
Abstract: 1287598 Electric signalling systems INTERNATIONAL BUSINESS MACHINES CORP 11 Dec 1969 [14 Jan 1969] 60457/69 Heading G4H In a communication system a transmitter transmits a frequency-modulated signal, and each of a plurality of receiving stations incorporates a frequency demodulator 30 for demodulating the transmitted signal, the demodulator at each station having means to clamp the output within a preselected range so that the demodulator output varies only for frequency variation of the transmitted signal within a corresponding preselected range, the ranges being different for each of the receivers. The demodulator converts the incoming frequency signal into an amplitude signal linearly related to the frequency. This is applied to a pair of clamps 40, 50, the clamping level of which is set by potentiometers 42, 52. Clamp 40 sets an upper level so that if the signal is above this level a constant maximum voltage is produced at point 33. If it is below a certain level clamp 50 sets a constant minimum voltage at 33. If the level changes within this range a corresponding changing voltage is produced at 33. The signal at point 33 for three receivers is shown in Fig. 4. The signal at 33 is differentiated at 60 and the output is applied to single shots 61, 62 responding to signals of different signs. A frequency transition from f1 to f2 causes the first station S1 to indicate a binary "0" and the opposite transition, a binary "1". The other stations do not respond.

Title: Improvements in or relating to spreading implements
IPC: E01C19/20
Filed: 1968-12-23
Abstract: 1,247,730. Spreading implement. C. VAN DER LELY N.V. 23 Dec., 1968 [27 Dec., 1967], No. 61168/68. Heading AID. A spreading implement has two control member plates 43, 44 situated beneath the opening 64 in the hopper 27. Material leaving the hopper passes through holes 66, 67 and 69, 70 in the plates to reach a spreading member 15 attached to a rotatable shaft 14. A setting arm 52 is connected by rods 50, 51 to projections 46, 47 on the plates and can be turned about axis 53 by control lever 60 to move the plates about the axis of the shaft 14. The rods are positioned at different distances, 72, 73, from the shaft 53 so that one plate, 44, moves at a faster rate than the other. From a zero position in which each plate blocks the outlet in the other the plates move round for progressive settings of the lever 60 so that the opening in the faster plate overtakes and overlaps the opening in the slower plate allowing more material through. The ratio between the different rates of rotation is determined by the setting of the rods 50, 51 in holes 52A.  In a modification, Fig. 6, hopper has outlet 95, and two plates 96, 97 have outlets 98 which is similar to 95, and 110 which has one end tapered. Two setting arms 101, 105 are used to connect shaft 102 via rods 100, 104 to projections 99, 103 on the plates. The projections are on opposite sides of the central axis 111 and the setting arms are of unequal length and angularly spaced on shaft 102.
Patent GB-629762-A (GB)
Abstract: 629,762. Accounting machines. NATIONAL CASH REGISTER CO. July 28, 1947, No. 24448/48. Convention date, Jan. 30, 1941. Divided out of 629,707. Drawings to Specification. [Class 106 (i)] An accounting machine comprises an addsubtract totalizer, a plurality of denominational orders of counting elements mounted co-axially with said totalizer, individual actuators for each of the counting elements, a zero stop for the lowest order actuator arranged to arrest the latter in either zero position or after only one step of movement, means normally effective to cause the zero stop to arrest the actuator in the zero position, control means to condition the machine to perform subtract operations, and means controlled by operation of said control means to move the zero stop so that the related actuator will be arrested after one step of movement to cause one unit to be entered additively into the counting elements during subtract operations. The embodiment described is the same as that disclosed in Specification 629,707 to which reference is made. Specifications 176,781, 227,852, [both in Class 106 (i)], 280,828, [Class 100 (iv)], 443,977 and 447,481 also are referred to.
Patent GB-651125-A (GB)
Abstract: 651,125. Electric totalizators. TOTALISATORS, Ltd. Dec. 15, 1948, No. 32468. Convention date, Dec. 17, 1947. [Class 106 (i)] In a totalizator system for doubles betting, each ticket machine D, E, ... has two rotary selectors F, H for manual selection of the competitor in the first and second events respectively, and both the grand total counter GT and the individual competitor-doubles combination counters, 1-1, 1-2, 1-3, ..., 2-1, 2-2, 2-3, ..., 3-1, 3-2, 3-3 ... &c. each consist of two magnets which are effective only when operated together. A doubles selection having been made the selector arms F, H are depressed to close switches F<SP>1</SP>, H<SP>1</SP> and remain locked in this position. When the distributer P connects up the operative ticket machine two parallel circuits are completed, over the left and right hand windings A, B of the grand total counter GT, respectively. Winding A is series-connected with winding N of the ticket machine trip-magnet, the selector F and all the left-hand windings of the counters C in the column corresponding to the first selection of the double. For example, if competitor numbered 2 is the first selection all the left-hand magnets 2 of the second column of counters C are energized. Winding B is series connected with winding O of the trip magnet, the selector H and all the right-hand windings of the counter C in the horizontal row corresponding to the second selection. Thus, for example, if competitor numbered 1 is the second selection all the right-hand magnets 1 in the first row of counters C are energized. The only counter C having both left- and right-hand magnets energized will thus be that selected by the selectors F, H, and this counter 2-1, the grand total counter GT and the trip-magnet NO, which also functions only when both magnets N, O, thereof are energized, operate to register the bet and to initiate a ticket-issuing cycle. One ticket machine only may be used, in which case the distributer P is unnecessary, and the ticket may be issued manually, the trip magnet then being dispensed with. The ticket machines may be arranged to print duplicate tickets which are retained in the machine for checking purposes.

Title: Spark ignition circuit
IPC: F23Q3/00
Filed: 1979-02-26
Abstract: A spark ignition circuit has the primary 12 of a spark transformer 11 connected in series with an SCR 5 across a capacitor 4. An SCR turn-off circuit, of diode 16 and inductor 13, is also included. The inductor 13 is coupled to the transformer 11 as shown. This results in a small net voltage in the inductor- SCR loop, so that the SCR current is kept low and it is turned off gently. This results in much less stress and heating on the SCR than in the prior art. The supply to the capacitor 4 may be from an AC source 1 via a diode 2 and an inductor 3. The capacitor may be charged from a DC to DC converter. <IMAGE>
Patent GB-2016313-A (GB)
Title: Clamping device
IPC: B25B5/08
Filed: 1979-03-21
Abstract: A clamping device is provided for holding non-uniform work pieces or clamping a slide in a slideway, comprising a row of wedges (33) in a guide track, with force transmitting members (36) between adjacent wedges. Closure together of the wedges along the track, or unequal pressure on the force transmitting members, causes certain of the force transmitting members to be moved perpendicular to the track by the cam action of the adjacent wedge members. There is thus obtained a substantially equal clamping action along the length of the row, whatever the length or shape of the track. The clamping device is particularly suited to replacing a gib strip in a machine tool provided with a slide. <IMAGE>
